Process annealing and full annealing are both heat treatment processes used to alter the properties of metals, but they serve different purposes and use different temperature ranges. Full annealing involves heating the metal to a temperature above its recrystallization point, followed by slow cooling, which results in a uniform microstructure and improved ductility. In contrast, process annealing occurs at lower temperatures, typically below the recrystallization point, and is used to relieve internal stresses and restore ductility without significantly altering the microstructure. This makes process annealing suitable for work-hardened materials, while full annealing is aimed at achieving a softer and more workable state.

spherodizing, normalizing, full annealing, process annealing, and stress relief
What is difference between annealing and normalizing?
The main difference between full annealing and normalizing is that fully annealed parts are uniform in softness (and machinablilty) throughout the entire part; since the entire part is exposed to the controlled furnace cooling. In the case of the normalized part, depending on the part geometry, the cooling is non-uniform resulting in non-uniform material properties across the part. This may not be desirable if further machining is desired, since it makes the machining job somewhat unpredictable. In such a case it is better to do full annealing.
What is the difference between full annealing and isothermal annealing?
Full annealing process consists of three steps. First step is heating the steel component to above upper critical temperature by 30 to 50 deg c, after suffciant soaking time parts will be cooled very slowly in the furnace. Where as for ISo Thermal annealing parts will be heated above upper critical temperature by 30 to 50 deg c, after suffciant soaking time parts will be transfered to intermediate temprature( Below the lower critical temperature) and allow to equalise the temperature then cool in air to Room temperature
